will avatar mtg have commander decks Avatar: The Last Airbender Comes to MTG, a New Mox Appears in Tarkir: Dragonstorm, and More Announced at MagicCon: Chicago Avatar Aang (Commander) | EDHREC

The only exception to this rule to my knowledge is Fists of Flame which costs 2 mana but can easily pump your army into lethal attackers

You may cast Spider spells and noncreature spells from the top of your library

I like it in multiple attack brews, aggro, tokens, and alongside Commanders that share combat damage triggers that you already invest in unblockable infrastructure like Whispersilk Cloak

Finally, we have Servant of the Conduit, which gives us an energy mana dork

The most important card to make these numbers good is Hell Mongrel

Being so light on colours this isn't going to be that helpful very often for fixing you so it is just a way to increase your chances of seeing the key cards like Ravager and Plating
